I ask only once a year: please help the Internet Archive today. Right now, we have a 2-to-1 Matching Gift Campaign, so you can triple your impact! Most can’t afford to give, but we hope you can. The average donation is $45. If everyone reading this chips in just $5, we can end this fundraiser today. All we need is the price of a paperback book to sustain a non-profit website the whole world depends on. We have only 150 staff but run one of the world’s top websites. We’re dedicated to reader privacy so we never track you. We never accept ads. But we still need to pay for servers and staff. I know we could charge money, but then we couldn’t achieve our mission: a free online library for everyone. This is our day. Today. To bring the best, most trustworthy information to every internet reader. I believe all of this is doable, if we pull together to create the internet as it was meant to be. The Great Library for all. The Internet Archive is a bargain, but we need your help. If you find our site useful, please chip in. Thank you.
